In the "moved state, the rectangle's position changes - to (50, 50). The added Transition specifies that when the rectangle - changes between the default and the "moved" state, any changes - to the \c x and \c y properties should be animated, using an \c Easing.InOutQuad. - - \snippet doc/src/snippets/declarative/transition.qml 0 - - Notice the example does not require \l{PropertyAnimation::}{to} and - \l{PropertyAnimation::}{from} values for the NumberAnimation. As a convenience, - these properties are automatically set to the values of \c x and \c y before - and after the state change; the \c from values are provided by - the current values of \c x and \c y, and the \c to values are provided by - the PropertyChanges object. If you wish, you can provide \l{PropertyAnimation::}{to} and - \l{PropertyAnimation::}{from} values anyway to override the default values. - - By default, a Transition's animations are applied for any state change in the - parent item. The Transition \l {Transition::}{from} and \l {Transition::}{to} - values can be set to restrict the animations to only be applied when changing - from one particular state to another. - - To define multiple transitions, specify \l Item::transitions as a list: - - \snippet doc/src/snippets/declarative/transitions-list.qml list of transitions - - If multiple Transitions are specified, only a single (best-matching) Transition will be applied for any particular - state change. In the example above, when changing to \c state1, the first transition will be used, rather - than the more generic second transition. - - If a state change has a Transition that matches the same property as a - \l Behavior, the Transition animation overrides the \l Behavior for that - state change. - - \sa {QML Animation and Transitions}, {declarative/animation/states}{states example}, {qmlstates}{States}, {QtDeclarative} -*/ - -QDeclarativeTransitionInstance::QDeclarativeTransitionInstance() - : m_anim(0) -{ -} - -QDeclarativeTransitionInstance::~QDeclarativeTransitionInstance() -{ - delete m_anim; -} - -void QDeclarativeTransitionInstance::start() -{ - if (m_anim) - m_anim->start(); -} - -void QDeclarativeTransitionInstance::stop() -{ - if (m_anim) - m_anim->stop(); -} - -bool QDeclarativeTransitionInstance::isRunning() const -{ - return m_anim && m_anim->state() == QAbstractAnimationJob::Running; -} - - -//ParallelAnimationWrapper allows us to do a "callback" when the animation finishes, rather than connecting -//and disconnecting signals and slots frequently -class ParallelAnimationWrapper : public QParallelAnimationGroupJob -{ -public: - ParallelAnimationWrapper() : QParallelAnimationGroupJob() {} - QDeclarativeTransitionManager *manager; - -protected: - virtual void updateState(QAbstractAnimationJob::State newState, QAbstractAnimationJob::State oldState); -}; - -class QDeclarativeTransitionPrivate : public QObjectPrivate -{ - Q_DECLARE_PUBLIC(QDeclarativeTransition) -public: - QDeclarativeTransitionPrivate() - : fromState(QLatin1String("*")), toState(QLatin1String("*")), - reversed(false), reversible(false), enabled(true) - { - } - - QString fromState; - QString toState; - bool reversed; - bool reversible; - bool enabled; - - static void append_animation(QDeclarativeListProperty<QDeclarativeAbstractAnimation> *list, QDeclarativeAbstractAnimation *a); - static int animation_count(QDeclarativeListProperty<QDeclarativeAbstractAnimation> *list); - static QDeclarativeAbstractAnimation* animation_at(QDeclarativeListProperty<QDeclarativeAbstractAnimation> *list, int pos); - static void clear_animations(QDeclarativeListProperty<QDeclarativeAbstractAnimation> *list); - QList<QDeclarativeAbstractAnimation *> animations; -}; - -void QDeclarativeTransitionPrivate::append_animation(QDeclarativeListProperty<QDeclarativeAbstractAnimation> *list, QDeclarativeAbstractAnimation *a) -{ - QDeclarativeTransition *q = static_cast<QDeclarativeTransition *>(list->object); - q->d_func()->animations.append(a); - a->setDisableUserControl(); -} - -int QDeclarativeTransitionPrivate::animation_count(QDeclarativeListProperty<QDeclarativeAbstractAnimation> *list) -{ - QDeclarativeTransition *q = static_cast<QDeclarativeTransition *>(list->object); - return q->d_func()->animations.count(); -} - -QDeclarativeAbstractAnimation* QDeclarativeTransitionPrivate::animation_at(QDeclarativeListProperty<QDeclarativeAbstractAnimation> *list, int pos) -{ - QDeclarativeTransition *q = static_cast<QDeclarativeTransition *>(list->object); - return q->d_func()->animations.at(pos); -} - -void QDeclarativeTransitionPrivate::clear_animations(QDeclarativeListProperty<QDeclarativeAbstractAnimation> *list) -{ - QDeclarativeTransition *q = static_cast<QDeclarativeTransition *>(list->object); - while (q->d_func()->animations.count()) { - QDeclarativeAbstractAnimation *firstAnim = q->d_func()->animations.at(0); - q->d_func()->animations.removeAll(firstAnim); - } -} - -void ParallelAnimationWrapper::updateState(QAbstractAnimationJob::State newState, QAbstractAnimationJob::State oldState) -{ - QParallelAnimationGroupJob::updateState(newState, oldState); - if (newState == Stopped && (duration() == -1 - || (direction() == QAbstractAnimationJob::Forward && currentLoopTime() == duration()) - || (direction() == QAbstractAnimationJob::Backward && currentLoopTime() == 0))) - { - manager->complete(); - } -} - - -QDeclarativeTransition::QDeclarativeTransition(QObject *parent) - : QObject(*(new QDeclarativeTransitionPrivate), parent) -{ -} - -QDeclarativeTransition::~QDeclarativeTransition() -{ -} - -void QDeclarativeTransition::setReversed(bool r) -{ - Q_D(QDeclarativeTransition); - d->reversed = r; -} - -QDeclarativeTransitionInstance *QDeclarativeTransition::prepare(QDeclarativeStateOperation::ActionList &actions, - QList<QDeclarativeProperty> &after, - QDeclarativeTransitionManager *manager, - QObject *defaultTarget) -{ - Q_D(QDeclarativeTransition); - - qmlExecuteDeferred(this); - - ParallelAnimationWrapper *group = new ParallelAnimationWrapper(); - group->manager = manager; - - QDeclarativeAbstractAnimation::TransitionDirection direction = d->reversed ?
